Tops off, ladies.

Bella Hadid, Madison Beer​ and ​​Charlize Theron ​are embracing July’s s​weltering​ ​temps​ — and their toned midriffs ​— in itsy-bitsy tops.

The look to beat is Kim Kardashian West’s, who went risqué for Balmain’s Los Angeles ​flagship​ opening last week. She​ flaunted her curvaceous figure in a ​sultry sports bra and an embellished, extra-high-slit sheer skirt courtesy of the French house.

These belly-baring ensembles​​​ are pretty much a hybrid of ​​naked dressing and athleisure. It’s sure to become a favorite among the fashion set and ​comfort-loving millennials alike.
